[xml] Error in schema or in xmllint?

[Roland Lezuo <roland lezuo rise tuwien ac at>]

The following schema defination produces the follwing error:

roland lezuo shswe:~/temp/libxml2-cvs$ xmllint --schema test2.xsd
Schemas parser error : Element decl.: A global declaration for
'PGPKeyPacket' is already existent.
WXS schema test2.xsd failed to compile


<?xml version="1.0"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema";

  <complexType name="PGPDataType">
    <choice>
      <sequence>
        <element name="PGPKeyID" type="base64Binary"/>
        <element name="PGPKeyPacket" type="base64Binary" minOccurs="0"/>
        <any namespace="##other" processContents="lax" minOccurs="0"

      <sequence>
        <element name="PGPKeyPacket" type="base64Binary"/>

      </sequence>
    </choice>
  </complexType>
 
 
</schema>

This is the errornous part of the xmldsig-core-schema.xsd file, I'm new
to xml but don't believe the xsd is buggy. All other choice tags are
working and this is the only <choice><sequence>... combination...

It libxml2 cvs from 2004-08-19
